Three new species of dorid nudibranchs from southern California, USA, and the Baja California peninsula, Mexico

Three new species of dorid nudibranchs, one phanerobranch Trapania goslineri, and two cryptobranchs, Peltodoris mullineri and Peltodoris lancei, have been found in the Gulf of California and nearby Pacific waters of the Baja California peninsula, Mexico, and southern California, USA. Trapania goslineri can be distinguished by its white body with large black blotches and yellow tips. Peltodoris mullineri is a large, yellow to golden orange dorid, with speckled brown blotches. Peltodoris lancei is a large, dark orange dorid, which has small white-tipped papillae and a very depressed body.
